The Pleiades star cluster is overhead at sunset now, which means they will exit the evening sky before you know it. Time to shoot them or wait a few months and get up early.
This was made from two nights imaging and about 64 three-minute subs, using my C11 with Hyperstar and an Antlia Triband RGB Ultra filter at the River Ridge Observatory.
I reprocessed an old image of the Whirlpool Galaxy from 2022 and the River Ridge Observatory.
Clouds and rain have forced me to reprocess some old images rather than acquire new ones. The image of the Rosette Nebula below was made from a session in 2021 and another from 2024. Both sessions involved the same camera and telescope but different dual narrowband filters which might explain why it turned out essentially monochrome. The two sessions totaled 3.5 hours of gathering light.
The Rosette Nebula is star forming region, those ones in the center, in the constellation of Monoceros, the Unicorn, to the left of Orion. Unless you are from the southern hemisphere, then it is to the right of Orion.
Celestron 11″ SCT with Hyperstar @f/1.9, ZWO ASI294MC Pro, L-Enhance and IDAS NBZ HS filters (not at the same time).
